Yes, it can grow incredibly slowly, but in good conditions it grows much faster.
That's all part of the commercialisation bit....and the desperate push for an easy claim to be carbon neutral and it's use as the offset for not doing enough to make real change in our use of fossil fuels otherwise.
Peat is the ultimate plant succession. It grows worldwide. I met a biologist years ago who worked everywhere from the tundra to Africa, from New Zealand to the Himalayas. Peat is everywhere.
Most of the damage to Scotland's peat is actually the burning to the heather that keeps the hunting shooting crowd happy....the moors are burned regularly and that damages the peat while keeping the heather regrowing to feed grouse, etc.,
It's use as fuel is as valid as woodburning, and in a land with no trees was the only fuel available.
There's no 'one size fits all'.
Peat as a crop is sustainable, but you need to look at beyond the screaming celebrity hype to find the other side.
"In Scotland, a small area of peatland (1-2,000 hectares from a total peatland area of over 2 million hectares across the country) is used for commercial peat extraction. Most is used for horticulture, a small amount for fuel and around 1% is used in the malting process of whisky production."

I believe and support the restoration of many of the peat bogs, but we need agriculture too, and a lot of the lowland bogs in Scotland and England were drained to produce good arable land.....land we still need and use.
Commercial sites have to restore their land, much like the opencast coal pits did. It's to their advantage to do so, because they can then crop it again.
Do I use peat ?
Yes.
After years of using alternative and constantly having to riddle through to remove plastic waste, etc., I give up. It's horrible stuff, it's polluted.
I tried the coconut fibre.....it's horrible, it's not native, it's infected with a white fungus too. I tried the cocoa waste, again not native, smells wonderful and it doesn't break down well. It's fine as a top dressing but that's it.
I tried the shredded paper, again it's polluted, ink, plastic, etc......and then there's peat. It works, it's clean, it is sustaintable, but it's use is filled with all the umbrage of the screaming banner headlines.
The reality is that we actually use a tiny percentage of the peat bogs for horticulture, and we'd be much better off to accept it as a crop and restore while still working to repair peat bogs as and where possible.....and that includes the high grouse moors.
I compost every thing I can. From leaf litter to veg peelings, from prunings to the old pot fill. I have three active bins and two active dalek type ones....they are worm worked and they make beautiful sustainable, and clean, compost.
I use peat to over winter things like begonias, to mix to make the water retention compost for my seed trays and houseplants.
I've tried the alternatives. They're carp.
I actually grow peat ....I'm on heavy clay soil, we're always damp.....and I deliberately grew spaghnum moss just to see.
It grows like a weed and cheerfully overflows pots. It rots down below and only the top green layer is growing. I lifted off the top layer and after a year there was an accumulation of about an inch of dark rust brown peat below. Very open and porous, but it was peat. Compressed down it was still more than the claim of less than a mm a year.
So, up to yourselves, but I'm fed up of the rubbish alternatives. I prefer to have what would actually grow here, and I am getting to old to riddle through sacks of compost to take out post consumer plastic. I refuse to add that stuff to my garden if I can at all avoid it.
